Bollock dagger - Bollock daggers, also known as kidney daggers from Victorian times to save the blushes of anyone reading about the medieval weapons, were carried by everyone from peasants to knights. They were not only a supplementary fighting weapon, alongside swords, but also used as knives for cutting anything from vegetation to food. The name comes from the two oval protrusions on the hilt. You can see a great example at Norwich Castle Museum. Bollock dagger at Norwich Castle Museum - Credit: Norfolk Museums Service
